    Re: Noisy extractor motor

    Is it a capacitor induction motor ? Electrolytes in these capacitors change over the time and they lose their ability to shift the phase.

    Then you need to do math: 100% - 81.4%.
    You get 18.6%.

    Are you aware that it is not 18.6% on the...

    Re: Mold inside inner cover and top of frames

  12. Re: Bees stopped building comb in TBH--should I worry?

    Once they are hatched out, they will look for open honey cells.
    These young bees will compete for food with the older bees. Older bees are stronger. It is good to have fresh nectar coming in.

    Re: condensation in TBH

    I would consider placing a thin styrofoam plate on the outer side of the pane to keep it warmer.
    In that way you can prevent the vapor condensation inside.
